The new mom captioned the super-cute photo of her baby's tiny foot, “Welcome to the world baby Alaska! Your little feet absolutely rocked my world, I've never been so in love! @acahan and I couldn't be more proud."

The 29-year-old Sports Illustrated swimsuit model later posted another photo of herself pushing a baby stroller down the street, which she captioned, "Out on the town."

Anne and Adam have not yet officially revealed the gender of their newborn, but some are speculating that little Alaska is likely a girl, considering the pink polka dots on the baby blanket, and the pink balloons Anne got for her baby shower a few weeks ago.

Although it's always possible the couple is just subverting traditional gender tropes and expectations.
